 MICROPHONE CONNECTOR [MIC]

  Accepts an optional microphone.

  • See page 15-4 for appropriate microphones.
  • See page 2-10 for microphone connector information.

i

 MIC GAIN CONTROL [MIC] 

(p. 3-12)

  Adjusts microphone input gain.

  •  The transmit audio tone in the SSB, AM and FM modes 

can be adjusted independently in set mode. (p. 12-5)

✔

 How to set the microphone gain.

Set the [MIC] control so that the ALC meter occasionally 
moves up-scale during normal voice transmission, in the 
SSB, AM or FM mode.

o

 VOX SWITCH 

VOX

 

 

➥

  Push to turn the VOX function ON or OFF dur

-

ing SSB, AM and FM mode operation. (p. 6-2)

 

➥

  Hold down for 1 second to enter VOX set mode. 

(p. 6-2)

✔

 What is the VOX function?

The VOX function (voice operated transmission) acti

-

vates transmission without pushing the transmit switch 
or PTT switch when you speak into the microphone; then 
automatically returns to receive when you stop speaking.

!0

 RF POWER CONTROL [RF PWR] 

(p. 3-12)

   Continuously varies the RF output power from a 

minimum of 5 W* to a maximum 

of 200 W*

.

  *AM mode: 5 W to 50 W

!1

 BREAK-IN SWITCH 

BK-IN

 

   Push to turn the break-in function ON 

(semi-break-

in, full-break-in)

 or OFF during CW mode operation. 

(p. 6-3)

✔

 What is the break-in function?

The break-in function switches transmit and receive with 
CW keying. Full break-in (QSK) can monitor the receive 
signal between CW dots and dashes.

!2

  ELECTRONIC CW KEYER SPEED CONTROL 

[KEY SPEED]

 (p. 4-4)

   Adjusts keying speed for the internal electronic CW 

keyer.

  •  6 wpm (minimum) to 48 wpm (maximum) is the adjust

-

able range.

!3

 MONITOR SWITCH 

MONITOR

 (p. 6-4)

  Monitors your transmitted IF signal.

  •  The CW sidetone functions regardless of

switch setting in the CW mode.

  •  The [MONITOR] indicator above this switch lights 

green while the function is activated.

!4

 BREAK-IN DELAY CONTROL [DELAY]

 (p. 6-3)

 

 

Adjusts the transmit-to-receive switching delay 
time for CW semi-break-in operations.

!5

 AGC CONTROL [AGC]

 (p. 5-12)

 

 

Adjusts the continuously-variable AGC circuit time 
constant.

  •  To use [AGC] control, push 

AGC VR

cator lights).

!6

  SQUELCH CONTROL [SQL]  

(outer control; p. 3-9)

   Adjusts the squelch threshold level. The squelch 

mutes noise output from the speaker (closed con-
dition) when no signal is received.

  •  The squelch is particularly effective for FM. It is also 

available in other modes.

  •  The 11 to 12 o’clock position is recommended for the 

most effective use of the [SQL] control.
